discharge orifice

In such a case, proceed therefore with the burner adjusted to 10 cm below the discharge orifice with a 12 cm flame height.

The air gap in this case is the vertical distance from the lowest point of the discharge orifice which discharges into the receptacle, to the top of the weir overflow.

The fangs have a ridge at the tip lateral to the discharge orifice, as well as a blade-like structure on the ventral surface otherwise seen only in some opistoglyphous and atractaspid snakes.
